PATENT PHILIPI HERBERT, OF ST. LOUIS, MISSOURI.

IMPROVEMENT IN eANe-PLows.

Specification forming part of Letters Patent No. 93,6l8. dated Augustl0, 1869.

lo all whom it may concern,.-

Beit known that I, PHILIP? HERBERT, of St. Louis, in the county of St.Louis and State of Missouri, have made certain new and usefulImprovements in Gang-Flows; and I do hereby declare that the followingis a full and clear description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon. l

The nature of this invention is in the niaiiner of connecting the wheelto the axle ofthe plow, in the method of raising the plows and gagingthe depth thereof, and supporting the plow-beanis, and in thearrangement of draftpole for adjusting the direction of the draft to thecutting of the plow, all of which will hereinafter more fully appear.

To enable those herein skilled to make and use my said improvements, Iwill now fully describe the same, referring to Figure l as a sectionalside view at line y z of plan; to Fig. 2 as a plan; to Fig. 3 as a frontView; and to Fig. 4 as a rear view, showing the arrangement of my saidplow in its usual construction. Fig. 5 is a part bottom view of thetongue attachment.

I support the axle A upon the wheel A on the one side in the mannerusual in ordinary vehicles. On the other side I support the said axle onthe wheel A2 in an adjustable manner as to height, as follows: To the-under side of the axle A, I secure by eyebolts or staples the axle-bara, usually of wrought-iron. On said bar will be clamped the woodentree-journal B, on which the wheel A2 is arranged in the ordinarymanner. The endl of the axle A has an indented sector, C, thereon. Intothe indentations c thereof the pawl d engages, said pawl being connectedwith alever, D, and operated by a hand-rod, D', and link d. A spring,d2, keeps the rod D in such position that the pawl remainsin'engagenient on the sector C unless operated by hand. If, therefore,the pawl is raised, the operator, by using the lever D to turn thetree-journal B, may regulate the position of the axle of the wheel A2 tothe axle A, and in this Way bring the axle A into proper height and gagethe depth of the plows in ground.

On the axle A, I arrange the posts E, supporting the seat of the driver,and under said axle I secure thereto the tongue-pieces F, which at theirforward ends carry the front board F', to which the pole G is attached,being hinged thereto at the pivot-bolt g. In order to incline the pole Gfrom a line per pendicular to the axle A, and thereby cause thedraft-teani to pull the plows toward or from the land into which theyare cutting, I arrange the slot f in the front board, F', and regulatethe position of the pole G by setscrew or bolt g in said slot. Saidset-screw g affords also a point of attachment for the link lz, whichsupports the swivel-bolt 71, of the double-tree H, the pole G actingwith the link 7L to support said bolt h. On said tonguepieces F, Isupport the standards I, having a cross-bar, z'. Said standards supportone end of the fulcrum-pieces K, these being further supported on theposts E. At the rear ends of the pieces K they are notched for ajournalA seat for the pivot-bar L, on which the forked lever L vibrates.Said lever is limited in its upstroke` by the cross-bar i, and at itsrear end supports, by hinged hanger-rods Z, the plowbeams M. vTheplow-beams extend forward to a rest on the axle A, and are laterallyguided by guide-plates, Fig. `3, which are secured in the axle. Vhen theplow-beams are to be raised to throw the plows out of ground, theoperator, by his foot, depresses the lever L and brings its forward endunder the detainer` bar L2, which is hinged to one of the standards I,and thenv holds down the lever LG The plow-beams M form a frame of twoparallel' pieces joined by transverse slots m, and secured relatively toeach other by proper bolts or stirrup-clainps generally, as indicated inFigs. 1, 2, and 4. At their rear ends these beams support the standardsa of the plows N. 'Ihe standards n have horizontal arms n', pivoted inthe beams M at proper pivot-bolts, a2, and wooden pins a2 prevent theplows from rising up. At the same time a suitable strapplate, at,passing under the arms a prevents the plow from dropping down. In caseof a jam or other impediment in the movement of the plow, the wooden pinn3 will break, and the plows may then lift out of ground, Qturning onthepivot m2,) and thus avert serious injury. It may be advantageous toform an arm, a5, as

an extension 'of the arm n', into which the holes for the pin a2 may be`made, and thus the plow-standards n will not be weakened.

When the plows run in ground too deeply,

I raise the forward end of the plow-beam M,

thereby tilting the ploWs and raising the point of the plowshare andrelieving it of draft in the manner following: The lever O connects withthe crank O', which vibrates in journals o on the tongue-pieces F. Thensaid lever is moved forward, the crank O approaches a vertical position,and raises thc front end of the plow-beams M, as required. A rack, O, isused to hold the lever O in the position re quired. \Vhen the plows areraised out of ground by the lever L', owing to the attachment thereof atthe rear of the beams M, these Will incline to tip up, their forwardends risfrom this crossbar Z/ the beams M may then be disconnected.

Having thus fully described my said invention, what I claim is- 1. Theaxle-bar a, tree-journal B, and seetor and pawl devices for connectingthe Wheel A2 with the axle A, substantially as set forth.

2. The front board, F', pivot g, link h, and pole G, connectedadjnstably by the slot f and setscrews f', substantially as set forth.

3. The standard I, lever L', bar L2, fulcrum K, links Z, and cross-barZ', arranged in combination with the plow-beams M, substantially as setforth.

4. The lever O, crank O', link p, and roller P, supporting and operatingthe front end of the beams M, substantially as constructed and arranged.

5. The plows N, standards a, pins n, arms a', and pivot u, whenoperating substantially as set forth.

In witness of said invention I have hereunto set my hand.
